AHAs are water-soluble acids made from sugary fruits. They help peel away the surface of your skin so that new, more evenly pigmented skin cells may generate and take their place. After use, you鈥檒l likely notice that your skin is smoother to the touch.

Which acid should you choose ?聽
AHAs are primarily used for:
  • mild hyperpigmentation like age spots, melasma, and scars
  • enlarged pores
  • fine lines and surface wrinkles
  • uneven skin tone

Although AHAs are often marketed as safe for all skin types, you鈥檒l want to take care if you have extremely dry and sensitive skin. You may need to gradually work up to daily use to avoid irritating your skin.

Which AHA to use ?

All AHAs yield significant exfoliation. Still, the effects and uses can slightly vary between types of acids. Your selected AHA should have a maximum concentration between 10 and 15 percent. Apply new products every other day until your skin gets used to them. This will also reduce the risk of side effects, such as irritation.

No matter which AHA you choose, the strong exfoliating effects make your skin more sensitive to the sun. Wear sunscreen every morning to prevent burns, age spots, and increased skin cancer risks.

Glycolic聽

It鈥檚 also made from a widely available plant: sugar cane. Glycolic acid provides significant exfoliation. This makes it an all-around treatment for many skin concerns. And thanks to its antimicrobial properties, it may even help prevent acne breakouts.

Lactic聽

Unlike other AHAs made from fruits, lactic acid is made from lactose in milk. It鈥檚 also known for its significant exfoliation and anti-aging effects.

Mandelic

It聽contains larger molecules derived from almond extracts. It can be combined with other AHAs to increase exfoliation. Used alone, the acid may improve texture and pore size.

Difference with BHA ?聽

BHAs, on the other hand, are primarily used for acne and sun damage. These products go deep into your hair follicles to dry out excess oils and dead skin cells to unclog your pores. Because of these effects, BHAs are most suitable for combination to oily skin. Lower concentrations may be used to help calm sensitive skin. You may also have more success with BHAs if you wanted to reduce rosacea-related redness.

Can I combine AHA and BHA products ?
AHAs and BHAs yield fuller skin when used together. This may be due to increased collagen production, which can make both the dermis and epidermis visibly plumper.

NOTE : Still, you don鈥檛 want to layer AHAs and BHAs on top of one another. These are both exfoliators, so using both can cause dryness and irritation.

Tips聽

You could also use AHAs and BHAs on alternating days. This method works well if you鈥檙e using at-home chemical peels that contain AHA.

Another strategy is to use these acids on certain parts of your face only. For example, you can apply an AHA to dry areas and a BHA to oily areas if you have combination skin.
